ExistingStuffType type of temporally and spatially stuff-like thing A collection of collections, and a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVny6pwpEbGdrcN5Y29ycA" class="cyc_term">ExistingStuffType</a> is a collection of things (including portions of things) which are both temporally and spatially stufflike. Division in time or space does not destroy the stufflike quality of the object (down to a certain granularity). <p/> <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> <b>STUFFTYPE</b> <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVny6pwpEbGdrcN5Y29ycA" class="cyc_term">ExistingStuffType</a>)</code> implies both (i) for most instances <code><b>STUFF</b></code> of <code><b>STUFFTYPE</b></code>, for any proper physical part (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r8a2smPXcQdiEoJhcx65EiQ" class="cyc_term">properPhysicalDecompositions</a>) <code><b>PART</b></code> of <code><b>STUFF</b></code>, <code><b>PART</b></code> is also an instance of <code><b>STUFFTYPE</b></code> and (ii) for all instances <code><b>STUFF</b></code> of <code><b>STUFFTYPE</b></code>, for most proper physical parts <code><b>PART</b></code> of <code><b>STUFF</b></code>, <code><b>PART</b></code> is also an instance of <code><b>STUFFTYPE</b></code>. <p/> For example, every piece of wood is temporally stufflike: if W-168 is a piece of wood during 1996, then it's also a piece of wood for the one-minute time-slice 9:05am 7/7/96. It's also spatially stufflike: if we take that piece of wood W-168 and cut it in half, we have two things which are both pieces of wood. Since every piece of wood is both temporally and spatially stufflike, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVimxJwpEbGdrcN5Y29ycA" class="cyc_term">Wood</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVny6pwpEbGdrcN5Y29ycA" class="cyc_term">ExistingStuffType</a>. Other instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVny6pwpEbGdrcN5Y29ycA" class="cyc_term">ExistingStuffType</a> include the collections <font color="#ff0000">#$AppleJuice</font>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj1EpwpEbGdrcN5Y29ycA" class="cyc_term">IceCream</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvgC2UJwpEbGdrcN5Y29ycA" class="cyc_term">Diamond</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwQCaCZwpEbGdrcN5Y29ycA" class="cyc_term">WaxedPaper</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwAoze5wpEbGdrcN5Y29ycA" class="cyc_term">StriatedMuscle</a>.
